Specification of Letters Patent.

Application filed December s, 1915. serial no. eaoie.

T 0 all whom it may concern:

Be it known that I, FRANK J. VERBA, a citizen of the United States, and a resident of Colorado Springs, in the countyof El Paso and State of Colorado, have invented a new and useful Improvement in Laryngoscopes, of which the following is a specification. r

My invention is an improvement in laryngoscopes, and the'invention has for its object to provide a device "of the character specified especially adapted for treating taoercular affections of the larynx-by the direct application of sun rays to the diseased parts, and wherein the device is so arranged and constructed that the patient may treat himself by either reflection, that is, conveying the healing and anasthetic infra-red rays into the larynx; or by refraction, that is, by conveying the germ destroying 'ultra violet or actinic'rays in the same manner.

In the drawings :-Figure 1 is a front viewot the improved laryngoscope', Fig. 2 is a side view at right angles to Fig. 1, Fig, 3 is a. top plan view, and Figs. 4 and 5 are sections on the lines H and 55, respectively, of Fig. 2, each view looking in the direction of the arrows adjacenttothe line.

In the embodiment of the invention shown I in Figs. 1 to 5 a substantially Ushaped frame is provided, consisting of a body 1 and arms 2 and 3, extending laterally from the body in the same direction and in spaced parallel relation.

A double convex lens 4 arranged, within the circular frame 5 in the usual manner is connected with the body 1 of the frame, a

stall or handle 6 being connected to the frame 5 of the lens. This staff or handle is provided with an angular engages a nipple'S on the frame, and the stall or handle 6 is mounted to slide in a sleeve 5), connected with the frame in a man ner to be presently described, and the staff is held in adjusted position with respect to the sle vs by a-set screw 10, which is threaded through the sleeve into engagement with the stafi'. v

The sleeve is provided with a radial arm having a ball, 11 at the free end thereoi, and this ball 11 is engaged between parallel clamping plates 12. The ball 11 is at one end of the'said plates and attheir other. end 1 the plates 12 are arranged on opposite sides of the body 1 of the frame 1*23, and the plates are clamped on the body and on the portion 7 which ball by a set crew 13, which is rotatabiy mounted in one of? the plates and has a threaded engagement with the other. it will be obvious that with this. arrangementthe position of the stafi with respect to the gt'rame may be varied and when the parts are l in adjusted position the clamping plates 12,

may be clamped on the ball and the body to hold the parts in said adjusted position.

A concave mirror l-l is mounted on the Patented July at, fLQZlfi.

arm 2 ofthe frame, tl1e.,said mirror being Y connected with a-stail or handle-l5-,=by means of. a clamp corresponding to the clamp 1.2-13, just described. The mirror la is pro} vided on its convex face with an arm ex-H tending laterally from the mirror, and having a ball 16 at its free end. The'stafi' or handle provided with a similar ball.

17, and clamping plates '18 similar to the plates 12 are engaged with the balls, the plates being on opposite sides or the balls and being clamped on the balls by a set screw 19. The set screw is jonrnaled in one of the plates and has a threaded engagement with the other.

A flat mirror: 20 is mounted. on the'arni 3 of the frame, the mirorr being connected to a stall or handle 21 in the same-manner as the mirror 14: connected to the stafi' or handle 15. The mirror has a ball 22 similar to the ball 16 and similarly mounted, .andthc stall or handle has a ball 23. These balls are. clamped between plates 24-, corresponding to the plates 12 and 18. and the plates are clamped on the balls by a screw The plates i2---18--2l aresinnlar in one respect, namely, each plateis' recessed at its ends and on its inner face to receive the balls. In the case of the plates 12; the re- 85 cesses for receiving the body are transverse shown more particularly in Fig. i is mount ed to slideon the arm o1 the frame, and each sleeve is held in adyusted. position by means of a set screw 26, each set screw be;

ing threaded through an opening in the sleeve into engagement with the frame arm.

Tl'ie statfsor handles 15 and 21 are slidably connected with in Fig. l. A clampinghlock 27 is arranged at one side of each sleeve and each of the .said blocks is adjnstahly connected to the the sleeves as shown 23 inns 1 sleeve by means of a set screw 28. Each of the set screws is ournaled in on open ing in the block and engages an internally threaded opening in the sleeve.

5 Each block is grooved transversely to receive the stall -2l as the case may be, and since each block is in ell c pivoted to the sleeve by the set screw 28 it will be obvious that either stall or handle ma swung at; an angle with ct to the Sllik, as indicated in dotted lines 101 the stall 21.

' 2. The stalls or handles may i also a justed longitudinally b5 loos ning the screw 28 and they may be adu vertically with respect to the Y loosemng the set screw Means pr'vided in connection with the 'fraine 123 for permit he cornice-lied with ch v.ir bi,

to support the name in up Tl'ie said mechanism comprises a bar or rod 29 connected with each arm 2 of he flacli ol the ll bars orrods has its upper end oil'set toward clamping" ii: frameas indicated at 30, and the said upper end 15 received n one of the openings of a double sleeve 31. This sleeve iiwo parallel openings, one oi. which is eng z -ed, by the ad acent arm 2 or 3, as the 30 ea c may be, while the other engaged by the offset portion of the a iacent bar or rod.

screws 32 A through the sleeves at oppof for en; ll and the o feel portion of the c and it will be noticed th s '25) and of the arms L or ard to facilitate their eineni; 49 with the chair back indicated in oiled lines 'l-iien the set screws and ar on the bars and on the erms "*9 are held in spaced Jarallel reletin with respect to the arms, and ti said lars form a species of clamp fruit-permitting the me to be su 'iported in the manner men- LIOI'iGCl. Each of the mirrors 1% and 20 is connected to its staff or handle 15 or 21 by so a universal joint coi'inection, and each of the said connections is capable being rigid- I threaded ized or fixed so that the mirrors :1 y be held in adjusted position. The same is "true end thereof, stall. or handle or the lens and having a raheight of the frame 1 -2-3 with respect to the surface of the ground may be varied by means of the clamp 29303l.

In use the mirror 14 is utilized to reflect the rays into the throat. The mirror 20 which is a plain mirror is provided to permit the operator to see and understand What he doino giving a reverse picture of the interior or the throat. In addition to re lieetinf the rays the mirror 14 also collects the ra. and causes them to be converged upon the point desired, that is, on the throat mirror when used or on the parts to be treated.
